As shown in fig. 3, the level of the connection point of the first side die hinge base 22 to the bottom die 02 is located between the center of gravity M of the first side die 03 and the lower surface of the bottom die 02, so that the first side die 03 can rotate about the connection point.

The number of the first side mold connecting legs 05 may be one or more. The number of the first pin shafts 21 and the first side die hinge bases 22 is equal to the number of the first side die connecting legs 05, and the first pin shafts 21 and the first side die hinge bases 22 correspond to the first side die connecting legs 05 one by one. In practical applications, when the length of the first side die is shorter, the number of the first side die connecting legs 05 may be set to be smaller, and when the length of the first side die is longer, the number of the first side die connecting legs 05 may be set to be larger. Fig. 2 shows a structure of two first side mold connecting legs 05, a first pin 21 and a first side mold hinge base 22, which can realize the movable connection between the lower ends of the first side mold connecting legs 05 and the bottom mold 02 without increasing the manufacturing difficulty.

In another possible manner, the lining segment production mold may further include a hinge, and the hinge is used to movably connect the lower end of the first side mold connecting leg 05 and the bottom mold 02. In this regard, the specific embodiment in which the movable connection between the lower end of the first side die connecting leg 05 and the bottom die 02 is realized by the hinge may refer to the related art and will not be described in detail herein.

It should be noted that, as for the implementation of the movable connection between the lower end of the second side mold connecting leg 31 and the bottom mold 02, reference may be made to the description of the movable connection between the lower end of the first side mold connecting leg 05 and the bottom mold 02, and the detailed description is omitted here.

First gyro wheel 07 and the upper end swing joint of first stand 08, second gyro wheel 09 and the upper end swing joint of second stand 10, the lower extreme of first stand 08 and the lower extreme of second stand 10 all with support 01 fixed connection. As shown in fig. 3, the first side die guide plate 11 has a first guide track surface 111, the first fixing surface and the first guide track surface 111 are two opposite surfaces on the first side die guide plate 11, a distance between an upper portion of the first guide track surface 111 and the first fixing surface is greater than a distance between a lower portion of the first guide track surface 111 and the first fixing surface, and the first roller 07 rolls along the first guide track surface 111. The second side die guide plate 32 is fixed to the outer side surface of the second side die 04 by a second fixing surface, the outer side surface of the second side die 04 is the surface of the second side die 04 away from the first side die 03, as shown in fig. 6, the second side die guide plate 32 has a second guide track surface 321, the second fixing surface and the second guide track surface 321 are two opposite surfaces of the second side die guide plate 32, the distance between the upper portion of the second guide track surface 321 and the second fixing surface is greater than the distance between the lower portion of the second guide track surface 321 and the second fixing surface, and the second roller 09 rolls along the second guide track surface 321.

The first roller 07 and the first upright column 08 are positioned on the outer side of the first side die, and the number of the first roller 07 and the first upright column 08 is equal and can be one or more. In practical applications, when the length of the first side die is shorter, the number of the first rollers 07 and the first columns 08 may be set to be smaller, and when the length of the first side die is longer, the number of the first rollers 07 and the first columns 08 may be set to be larger. Fig. 1 shows a structure in which the first roller 07 and the first upright 08 are two, and the movable connection between the first roller 07 and the upper end of the first upright 08 can be realized without increasing the manufacturing difficulty.

In order to realize the movable connection of the first roller 07 and the upper end of the first upright 08, in a possible manner, as shown in fig. 4, the lining segment production mold may further include a first lug plate 23, a second lug plate 24 and a second pin 25.

The first roller 07 is provided with a third through hole in the axial direction. One end of each of the first lug plate 23 and the second lug plate 24 is fixedly connected with the upper end of the first upright post 08, the plate surfaces of the first lug plate 23 and the second lug plate 24 are respectively provided with a fourth through hole and a fifth through hole, and the fourth through hole and the fifth through hole are opposite in position; the first roller 07 is located between the first ear plate 23 and the second ear plate 24, and the second pin 25 passes through the fifth through hole, the third through hole and the fourth through hole.

It should be noted that, the fixed connection between one end of the first ear plate 23 and one end of the second ear plate 24 and the upper end of the first upright post 08 may be welding. When the first ear plate 23 is fixedly connected with the upper end of the first upright post 08, the end surface of the first ear plate 23 may be the end surface of the first ear plate 23, or a part of the plate surface of the first ear plate 23 is fixedly connected with the upper end of the first upright post 08. Similarly, when the second ear plate 24 is fixed to the upper end of the first upright column 08, the end surface of the second ear plate 24 may be the end surface of the second ear plate 24, or a part of the plate surface of the second ear plate 24 may be fixedly connected to the upper end of the first upright column 08.

In another possible manner, a sixth through hole may be provided in the axial direction of the first roller 07, a groove may be provided at the upper end of the first column 08, and two seventh through holes may be provided on the side wall of the groove at opposite positions. Then, the first roller 07 is positioned in the groove, and the pin shaft penetrates through the sixth through hole and the seventh through hole to realize the movable connection of the first roller 07 and the upper end of the first upright column 08.

It should be noted that the second rollers 09 and the second columns 10 are located outside the second side mold, and the number of the second rollers 09 and the number of the second columns 10 are equal, and may be one or more. The movable connection between the second roller 09 and the second upright 10 can be realized by referring to the related description of the movable connection between the first roller 07 and the upper end of the first upright 08, and will not be described in detail here.

The lower end of the first upright post 08 and the lower end of the second upright post 10 can be fixed on the bracket 01 in a welding mode.

The upper portion of the first guiding track surface 111 and the lower portion of the first guiding track surface 111 may be respectively a plane or a curved surface, as long as the distance between the upper portion of the first guiding track surface 111 and the first fixing surface is ensured to be larger than the distance between the lower portion of the first guiding track surface 111 and the first fixing surface, so that when the lining segment production mold is vibrated by external interference, and the bottom mold 02 and the support 01 are separated for a short time, the mold opening of the first side mold 03 is not performed.

Similarly, the upper portion of the second guiding track surface 321 and the lower portion of the second guiding track surface 321 can be respectively a plane or a curved surface, so long as the upper portion of the second guiding track surface 321 and the interval of the second fixing surface are ensured, and the lower portion larger than the second guiding track surface 321 and the interval of the second fixing surface are ensured, so that when the lining segment production mold is subjected to external interference and vibrates, the bottom mold 02 and the support 01 are separated for a short time, and the second side mold 04 is not opened.

The bottom die 02 is arranged on the support 01, the support 01 is of a hollow structure, and the lifting end of the lifting mechanism 15 pushes the bottom die 02 to move up and down after penetrating through the hollow part of the support 01.

Wherein, the bracket 01 can be a frame structure, and the inside is provided with a transverse plate and a vertical plate which are connected with each other and used for placing the bottom die 02.

The lifting mechanism 15 may be a lifting cylinder, a lifting air bag, a jack, or the like. The number of the lifting mechanisms 15 may be one or more, as long as the lifting mechanisms 15 can be kept to push the basement membrane 02 to move up and down. Of course, in order to save cost and ensure that the lifting mechanism 15 stably pushes the bottom mold 02 to move up and down, as shown in fig. 2, the number of the lifting mechanisms 15 may be 4, and the lifting mechanisms may be uniformly distributed below the bottom mold 02. When the concrete implementation, elevating system 15 can vertically install on the mould station that opens and shuts of section of jurisdiction production line, and elevating system 15's lower extreme all is fixed on the ground. After the lifting end of the lifting mechanism 15 penetrates through the hollow part of the support 01, the bottom die 02 can be pushed to move up and down, and the bottom die 02 can be lifted stably.

In the present embodiment, the bottom mold 02 is placed on the support 01, and when the lifting mechanism 15 pushes the bottom mold 02 upward, the first roller 07 rolls downward along the upper portion of the first guide track surface 111, and at the same time, the second roller 09 rolls downward along the upper portion of the second guide track surface 321. Because the lower end of the first side die connecting leg 05 is movably connected with the bottom die 02, and the distance between the upper part of the first guide track surface 111 and the first fixing surface is larger than the distance between the lower part of the first guide track surface 111 and the first fixing surface, when the first roller 07 rolls to the lower part along the upper part of the first guide track surface 111, the first side die 03 can rotate around the connecting point of the first side die connecting leg 05 and the bottom die 02 to the direction far away from the second side die 04. Similarly, since the lower end of the second side mold connecting leg 31 is movably connected to the bottom mold 02, and the distance between the upper portion of the second guide track surface 321 and the second fixing surface is greater than the distance between the lower portion of the second guide track surface 321 and the second fixing surface, when the second roller 09 rolls downwards along the upper portion of the second guide track surface 321, the second side mold 04 rotates around the connecting point of the second side mold connecting leg 31 and the bottom mold 02 in the direction away from the first side mold 03. In this way, the first side mold 03 and the second side mold 04 can be automatically opened. Compared with the prior art, the side die is opened by loosening the fastening bolts one by one through manpower, so that the manpower and the time are saved, and the production efficiency of the lining segment is improved.

In addition, when the lifting mechanism 15 moves downward, the first roller 07 rolls along the lower portion of the first guide track surface 111 and the first side mold 03 rotates around the connection point of the first side mold connection leg 05 and the bottom mold 02 in a direction approaching the second side mold 04. Meanwhile, the second roller 09 rolls along the lower portion of the second guide track surface 321, and the second side mold 04 rotates around the connection point of the second side mold connection leg 31 and the bottom mold 02 in a direction close to the first side mold 03. In this way, the first side mold 03 and the second side mold 04 can be automatically closed. Compared with the prior art that the side die is closed by screwing the fastening bolts one by one through manpower, the manpower and the time are saved, and the production efficiency of the lining segment is improved.

It should be noted that the third roller 12 and the third upright 16 are located outside the first end mold 06, and the number of the third roller 12 and the third upright 16 is equal, and may be one or more. In practical applications, when the length of the first end mold 06 is shorter, the number of the third rollers 12 and the third pillars 16 may be set to be smaller, and when the length of the first end mold 06 is longer, the number of the third rollers 12 and the third pillars 16 may be set to be larger.

The upper portion of the third guiding track surface 191 and the lower portion of the third guiding track surface 191 may be respectively a plane or a curved surface, as long as the distance between the upper portion of the third guiding track surface 191 and the third fixing surface is ensured to be larger than the distance between the lower portion of the third guiding track surface 191 and the third fixing surface, so that when the lining segment production mold is disturbed by the outside to vibrate, and the bottom mold 02 and the support 01 are separated for a short time, the first end mold 06 is not opened.

Similarly, the upper portion of the fourth guiding track surface 201 and the lower portion of the fourth guiding track surface 201 may be respectively a plane or a curved surface, as long as the distance between the upper portion of the fourth guiding track surface 201 and the fourth fixing surface is ensured, and the distance between the lower portion of the fourth guiding track surface 201 and the fourth fixing surface is larger than that between the lower portion of the fourth guiding track surface 201 and the fourth fixing surface, so that the lining segment production mold vibrates due to external interference, and when the bottom mold 02 and the support 01 are separated for a short time, the mold opening of the second end mold is not performed.

In the present embodiment, the bottom mold 02 is placed on the support 01, and when the lifting mechanism 15 pushes the bottom mold 02 upward, the third roller 12 rolls downward along the upper portion of the third guide track surface 191, and at the same time, the fourth roller 14 rolls downward along the upper portion of the fourth guide track surface 201. Since the lower end of the first end mold connecting leg 17 is movably connected to the bottom mold 02, and the distance between the upper portion of the third guide track surface 191 and the third fixing surface is greater than the distance between the lower portion of the third guide track surface 191 and the third fixing surface, when the third roller 12 rolls from the upper portion to the lower portion of the third guide track surface 191, the first end mold 06 rotates around the connecting point of the first end mold connecting leg 17 and the bottom mold 02 in the direction away from the second end mold.

In some embodiments, as shown in fig. 3, the lining segment production mold provided in the embodiments of the present application may further include a first spring 30, a first end of the first spring 30 is connected to the first side mold connecting leg 05 to form a first connecting point, and a second end of the first spring 30 is connected to the first pillar 08 to form a second connecting point. When the first spring 30 is in a relaxed state, the distance in the vertical direction between the first connection point and the second connection point is not greater than the first threshold value.

It should be noted that the first connection point may be located at any position of the first side mold connection leg 05, and the second connection point may be located at any position of the first upright 08, as long as it is ensured that the distance between the first connection point and the second connection point in the vertical direction is not greater than the first threshold value when the first spring 30 is in the relaxed state. The first threshold may be set according to actual needs, as long as it is ensured that the first spring 30 is in an extended state when the lifting mechanism 15 pushes the bottom die 02 to move up and down. Fig. 3 shows a structure in which the first connection point is located at the middle of the first side mold connection leg 05 and the second connection point is located at the middle of the first upright 08.

According to the lining segment production mold provided by the embodiment of the application, the first spring 30 is arranged between the first side mold connecting leg 05 and the first upright post 08, when the lifting mechanism 15 upwards pushes the bottom mold 02, the first roller 07 downwards rolls along the upper part of the first guide track surface 111, the first spring 30 is stretched, and under the action of the tensile force of the first spring 30, the first roller 07 can be kept in close contact with the upper part of the first guide track surface 111. When the first roller 07 continuously rolls downwards along the first guiding track surface 111 to the lower part of the first guiding track surface 111, the pulling force of the first spring 30 is gradually increased, and then, when the lifting mechanism 15 continuously pushes the bottom die 02 upwards, the first spring 30 can urge the first side die 03 to rotate around the connection point of the first side die connection leg 05 and the bottom die 02 in the direction away from the second side die 04, so that the efficiency of opening the first side die 03 is improved.

When the first roller 07 rolls upward along the lower portion of the first guide track surface 111 while the lifting mechanism 15 supports the bottom mold 02 to move downward, the first roller 07 may be maintained in close contact with the lower portion of the first guide track surface 111 by the tensile force of the first spring 30. When the lifting mechanism 15 supports the bottom mold 02 to move downwards continuously, the first spring 30 can urge the first side mold 03 to rotate around the connection point of the first side mold connection leg 05 and the bottom mold 02 in the direction close to the second side mold 04, so that the efficiency of closing the first side mold 03 is improved.

It should be noted that, the lining segment production mold provided in the embodiment of the present application may not only set the first spring 30 between the first side mold connecting leg 05 and the first upright column 08, but also set the first spring 30 between the other side mold connecting legs and the corresponding upright columns, and further set the first spring 30 between the end mold connecting leg and the corresponding upright column, and for the specific setting manner, reference is made to the description above for setting the first spring 30 between the first side mold connecting leg 05 and the first upright column 08, and details are not described herein again.

In some embodiments, the lower portion of the first guiding track surface 111 in the embodiments of the present application includes at least a first portion and a second portion from top to bottom, and the distance between the first portion and the first fixing surface is greater than the distance between the second portion and the first fixing surface. The description of the second guiding track surface 321, the third guiding track surface 191 and the fourth guiding track surface 201 may refer to the description of the first guiding track surface 111, and will not be described in detail here.

Illustratively, the lower portion of the first guide track surface 111 is divided into a first portion and a second portion. The first portion may be in any plane between 30-60 degrees from vertical and the second portion may be in any plane between 0-60 degrees from vertical. No matter how the lower part of the first guiding track surface 111 is divided, the transition of the adjacent parts adopts the circular arc surface transition. The first guide locus surface 111 is not limited to a plane but may be a multi-step curved surface. The structure and description of the second guide track surface 321, the third guide track surface 191 and the fourth guide track surface 201 may refer to the structure and description of the first guide track surface 111, and will not be described in detail herein.

In some embodiments, the maximum distance between the first guide track surface 111 and the second guide track surface 321 in the embodiment of the present application is a first pitch, and the first roller 07 and the second roller 09 have a second pitch, which is smaller than the first pitch.

Illustratively, as shown in fig. 6, the maximum distance between the first guide track surface 111 and the second guide track surface 321 is C, the distance between the first roller 07 and the second roller 09 is C- Δ d, and C- Δ d is smaller than C.

In the embodiment of the present application, the second distance is smaller than the first distance, so that when the first side mold 03 and the second side mold 04 are in the closed state, the first roller 07 can apply an appropriate clamping force to the first side mold 03, so that the first roller 07 and the first guide track surface 111 are always in contact, and the second roller 09 can apply an appropriate clamping force to the second side mold 04, so that the second roller 09 and the second guide track surface 321 are always in contact.

In some embodiments, the maximum distance between the third guiding track surface 191 and the fourth guiding track surface 201 is a third distance, and the third roller 12 and the fourth roller 14 have a fourth distance therebetween, and the fourth distance is smaller than the third distance.

Illustratively, as shown in fig. 7, in the embodiment of the present application, the maximum distance between the third guiding track surface 191 and the fourth guiding track surface 201 is D, and the distance D- Δ D between the third roller 12 and the fourth roller 14 is smaller than D.

In the embodiment of the present application, the fourth distance is smaller than the third distance, so that when the first end mold 06 and the second end mold are in the closed state, the third roller 12 can apply a proper clamping force to the first end mold 06, so that the third roller 12 and the third guiding track surface 191 are always in contact, and the fourth roller 14 can apply a proper clamping force to the second end mold, so that the fourth roller 14 and the fourth guiding track surface 201 are always in contact.

In some embodiments, the vertical dimensions of the upper portion of the third guide track surface 191 and the upper portion of the fourth guide track surface 201 are greater than the vertical dimensions of the upper portion of the first guide track surface 111 and the upper portion of the second guide track surface 321. In this case, when the lifting mechanism pushes the bottom mold 02 to move upward, when the first roller 07 has moved to the lower portion along the upper portion of the first guide trajectory surface 111 and the second roller 09 has moved to the lower portion along the upper portion of the second guide trajectory surface 321, the third roller 12 also moves downward in the upper portion of the third guide trajectory surface 191 and the fourth roller 14 also moves downward in the upper portion of the fourth guide trajectory surface 201. Therefore, the first side die 03 and the second side die 04 can be opened first, and then the first end die 06 and the second end die are opened, namely, the end dies are opened after the side dies are opened first, so that die opening interference is avoided. For the convenience of understanding, the automatic mold opening and closing process of the lining segment production mold provided by the embodiment of the present application is described below with reference to fig. 8 and 9:

the automatic opening process of the side die comprises the following steps: as shown in fig. 8, the first guide track surface 111 and the second guide track surface 321 each include an upper portion and a lower portion, and the lower portion includes a first portion and a second portion. The lifting end of the lifting mechanism 15 moves upward to contact and push the bottom die 02 to rise relative to the support 01, so that the bottom die 02 and the support 01 are gradually separated, the first roller 07 starts to roll from the upper part to the lower part along the first guide track surface 111, and the second roller 09 starts to roll from the upper part to the lower part along the second guide track surface 321. When the first roller 07 rolls down on the first guide track surface 111, the first side mold 03 is always closed, and when the second roller 09 rolls down on the second guide track surface 321, the second side mold 04 is always closed. In this process, the first spring 30 is gradually extended, and the first roller 07 can maintain close contact with the upper portion of the first guide track surface 111 and the second roller 09 can maintain close contact with the upper portion of the second guide track surface 321 by the tensile force of the first spring 30. As the lifting end of the lifting mechanism 15 continues to move upward, the first roller 07 rolls on the first portion of the first guide track surface 111, and the second roller 09 rolls on the first portion of the second guide track surface 321, during which the first spring 30 continues to be stretched, so that the first side mold 03 rotates around the connection point of the first side mold connection leg 05 and the bottom mold 02 in the direction away from the second side mold 04 under the combined action of gravity and spring tension, and the second side mold 04 rotates around the connection point of the second side mold connection leg 31 and the bottom mold 02 in the direction away from the first side mold 03 under the combined action of gravity and spring tension. When the first roller 07 moves to the second portion of the first guide track surface 111, the first side mold 03 is opened to the maximum, and thus the first side mold 03 is automatically opened, and simultaneously, the second roller 09 moves to the second portion of the second guide track surface 321, and the second side mold 04 is opened to the maximum, and thus the second side mold 04 is automatically opened.

The automatic opening process of the end die comprises the following steps: as shown in fig. 9, the third guide track surface 191 and the fourth guide track surface 201 are divided into an upper portion and a lower portion. The opening process of the first end mold 06 and the second end mold is similar to the opening process of the first side mold 03 and the second side mold 04, but in order to avoid mold opening interference, the upper parts of the third guide track surface 191 and the fourth guide track surface 201 are longer than the upper parts of the first guide track surface 111 and the second guide track surface 321, so that the first side mold 03 and the second side mold 04 of the lining segment production mold can be opened first during mold opening, and then the first end mold 06 and the second end mold can be opened.

Specifically, the lifting end of the lifting mechanism 15 moves upward to push the bottom mold 02 to rise relative to the support 01, so that the bottom mold 02 and the support 01 are gradually separated, the third roller 12 starts to roll downward along the upper portion of the third guide track surface 191, and the fourth roller 14 starts to roll downward along the upper portion of the fourth guide track surface 201. The first end mold 06 is always kept closed when the third roller 12 rolls down on the upper portion of the third guide track surface 191, and the second end mold is always kept closed when the fourth roller 14 rolls down on the upper portion of the fourth guide track surface 201. Only after the first roller 07 rolls to the first portion of the first guide track surface 111 for a certain distance and the second roller rolls to the first portion of the second guide track surface 321 for a certain distance, the third roller 12 starts to roll to the lower portion of the third guide track surface 191 and the fourth roller 14 starts to roll to the lower portion of the fourth guide track surface 201. With the continuous upward movement of the lifting end of the lifting mechanism 15, the third roller 12 continues to roll along the lower portion of the third guide track surface 191, the first end die 06 rotates around the connection point of the first end die connection leg 17 and the bottom die 02 in the direction away from the second end die under the action of gravity until the lifting end of the lifting mechanism 15 moves upward to the maximum distance, and the first end die 06 is opened to the maximum, so that the automatic opening of the first end die is realized. Meanwhile, the fourth roller 14 continues to roll along the lower portion of the fourth guiding track surface 201, and the second end mold rotates around the connection point of the second end mold connection leg 18 and the bottom mold 02 in the direction away from the first end mold 06 under the action of gravity until the lifting end of the lifting mechanism 15 moves upwards to the maximum distance, and the second end mold is opened to the maximum, so that the second end mold is automatically opened.

When the first side die 03, the second side die 04, the first end die 06 and the second end die are all opened, the cast lining segment can be taken out from the cavity for accommodating the lining segment. After that, a mold clamping process is performed. After the mold is closed, the pouring of other lining segments can be carried out.

The compound die order and the die sinking order of lining segment production mould that this application embodiment provided are opposite, and when the die sinking, open first side mould 03 and second side mould 04 earlier, open first end mould 06 and second end mould again, so, when closing the mould, close first end mould 06 and second end mould earlier, close first side mould 03 and second side mould 04 again. The mold closing process of the lining segment producing mold will be described in detail below.

The process of automatic closing of the end die comprises the following steps: the lifting end of the lifting mechanism 15 moves downwards, the bottom die 02 descends under the action of gravity, the distance between the bottom die 02 and the support 01 is gradually reduced, the third roller 12 starts to move upwards along the lower part of the third guide track surface 191, the first end die 06 rotates around the connecting point of the first end die connecting leg 17 and the bottom die 02 to the direction close to the second end die under the action of gravity, and the first end die 06 is slowly closed. Meanwhile, the fourth roller 14 starts to move upwards along the lower portion of the fourth guiding track surface 201, the second end mold rotates around the connection point of the second end mold connection leg 18 and the bottom mold 02 to the direction close to the first end mold 06 under the action of gravity, and the second end mold is slowly closed. As the elevating end of the elevating mechanism 15 continues to move downward, the third roller 12 rolls to the upper portion of the third guide track surface 191, the first end mold 06 reaches the closed state, and at the same time, the fourth roller 14 rolls to the upper portion of the fourth guide track surface 201, the second end mold reaches the closed state.

It should be noted that, in the embodiment of the present application, springs may be disposed between the first end mold connecting leg 17 and the third upright column 16, and between the second end mold connecting leg 18 and the fourth upright column 13, and the arrangement of the springs is similar to that of the first spring 30 between the first side mold connecting leg 05 and the first upright column 08, and the arrangement of the springs is not described in detail herein.

When springs are also provided between the first end mold connecting leg 17 and the third upright column 16 and between the second end mold connecting leg 18 and the fourth upright column 13, the first end mold 06 will rotate around the connecting point of the first end mold connecting leg 17 and the bottom mold 02 in a direction away from/close to the second end mold under the combined action of gravity and the tensile force of the springs, improving the efficiency of opening/closing the first end mold 06. Similarly, the second end mold will rotate around the connection point of the second end mold connection leg 18 and the bottom mold 02 in a direction away from/close to the first end mold 06 under the combined action of gravity and the pulling force of the spring, improving the efficiency of opening/closing the second end mold.

The process of automatic closing of the side die comprises the following steps: the lifting end of the lifting mechanism 15 moves downward, the bottom mold 02 descends under the action of gravity, the distance from the bracket 01 gradually decreases, the first roller 07 starts to move upward along the second part of the first guide track surface 111, and the second roller 09 starts to move upward along the second part of the second guide track surface 321. When the first roller 07 rolls to the first portion of the first guide track surface 111, the first side mold 03 rotates around the connection point of the first side mold connection leg 05 and the bottom mold 02 to the direction close to the second side mold 04 under the combined action of gravity and the pulling force of the spring, and the first side mold 03 is slowly closed. Similarly, when the second roller 09 rolls to the first portion of the second guide track surface 321, the second side mold 04 rotates around the connection point of the second side mold connection leg 31 and the bottom mold 02 to the direction close to the first side mold 03 under the combined action of gravity and the pulling force of the spring, and the second side mold 04 is slowly closed. The lifting end of the lifting mechanism 15 continues to move downward, and the first side mold 03 reaches to be closed when the first roller 07 rolls upward along the first portion of the first guide track surface 111 to the upper portion of the first guide track surface 111, while the second side mold 04 reaches to be closed when the second roller 09 rolls upward along the first portion of the second guide track surface 321 to the upper portion of the second guide track surface 321.

After the first end mold 06, the second end mold, the first side mold 03 and the second side mold 04 are all closed, the lifting end of the lifting mechanism 15 continues to move downwards until the bottom mold 02 returns to the support 01. Finally, the lifting end of the lifting mechanism 15 continues to move downward, and can be separated from the bottom die 02. The lining segment production mold is kept matched under the action of gravity and the restraint of the support 01.

In the process of moving the lifting end of the lifting mechanism 15 downward until the bottom mold 02 returns to the support 01, the first roller 07 continues to move upward relatively along the first guide track surface 111, the second roller 09 continues to move upward relatively along the second guide track surface 321, and the spring tension of the first spring 30, the clamping force of the first roller 07 on the first side mold 03, and the clamping force of the second roller 09 on the second side mold 04 make the first roller 07 and the first guide track surface 111, and the second roller 09 and the second guide track surface 321 always in good contact in the process. Likewise, in this process, the third roller 12 and the third guide track surface 191, and the fourth roller 14 and the fourth guide track surface 201 are also in good contact at all times.

As described above, in the embodiment of the present application, the bottom mold is placed on the support, and when the lifting mechanism pushes the bottom mold upward/moves downward, the first roller rolls downward/upward along the upper/lower portion of the first guide track surface, and simultaneously, the second roller rolls downward/upward along the upper/lower portion of the second guide track surface. Because the lower ends of the first side mold connecting legs are movably connected with the bottom mold, and the distance between the upper part of the first guide track surface and the first fixing surface is larger than the distance between the lower part of the first guide track surface and the first fixing surface, when the first roller rolls along the downward/upward part of the upper/lower part of the first guide track surface, the first side mold can rotate around the connecting point of the first side mold connecting legs and the bottom mold in the direction away from/close to the second side mold. Similarly, the lower end of the second side mold connecting leg is movably connected with the bottom mold, and the distance between the upper part of the second guide track surface and the second fixing surface is larger than the distance between the lower part of the second guide track surface and the second fixing surface, so that when the second roller rolls along the downward/upward part of the upper/lower part of the second guide track surface, the second side mold can rotate around the connecting point of the second side mold connecting leg and the bottom mold in the direction far away from/close to the first side mold. In this way, automatic opening/closing of the first side mold and the second side mold can be achieved. Compared with the prior art that the side dies are opened/closed by loosening/screwing the fastening bolts one by one through manpower, the method saves manpower and time, and improves the production efficiency of the lining segment. In some embodiments, the lining segment production mold provided by the embodiment of the application can realize automatic opening and closing of the first side mold and the second side mold and can also realize automatic opening and closing of the first end mold and the second end mold. Compared with the prior art that the end mold is opened/closed by loosening/screwing the fastening bolts one by one through manpower, the method saves manpower and time and improves the production efficiency of the lining segment. In addition, in the embodiment of the application, the first springs can be arranged between the first side die connecting legs and the first stand columns and between the second side die connecting legs and the second stand columns, and the efficiency of opening and closing the side dies is improved. Set up first spring between first end mould connecting leg and third stand to and set up between second end mould connecting leg and fourth stand, improve the efficiency of opening and closed end mould.
